Hemophilia is a rare bleeding disorder in which your blood doesn't clot normally.
If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed internally, especially in your knees, ankles, and elbows. This bleeding can damage your organs or tissues and may be life threatening
Currently, about 17,000 people in the United States have hemophilia. About 1 in every 5,000 boys is born with hemophilia; girls are more rarely affected by this genetic condition linked to gender. A male can't pass the gene for hemophilia to his sons, though all his daughters will be carriers of the disease gene. Each male child of a female carrier has a 50% chance of having hemophilia
Human blood contains special proteins, known as clotting factors
. Identified by Roman numerals, clotting factors help stop bleeding and allow a blood vessel to heal after an injury. The last step in the clotting process (also called coagulation) is the creation of a "net" that closes the torn blood vessel and stops the bleeding This part of the process involves clotting factors VIII and IX. People with hemophilia are deficient in one of those factors due to their abnormal genes and, as a result, their blood can't clot properly.
hemophillia, also known as factor VIII deficiency, is the cause of about 80% of cases. Hemophilia B, which makes up the majority of the remaining 20% of cases, is a deficiency of factor IX. Patients are classified as mild, moderate, or severe, based on the amount of factor present in the blood.
